# node-red-contrib-diode
A Node Red node to isolate output from input. As messages are normally passed by REFERENCE, there 
may be times when you want to ensure that any changes you make to the output are not reflected back
to the input. This node will do that for you by making a copy of your message and passing it on.

Of course, passing an object by value uses up slightly more resources than passing by reference so depending on your objects and resources you might not wish to go TOO wild with this?

Oh and you'd want this for what reason? Should you use node-send to two outputs - and the first one passes onto a node that ALTERS say msg.payload - then your second output could find itself ALTERED! Attaching this node to the output in these circumstances could prevent such interference.

See http://tech.scargill.net/saturday-node-red-sermon for where this came from and why I created it thanks to feedback from blog readers and of course Dave CJ of Node-Red fame.
